Problems solved by technology

However, styrene has better applicability to unsaturated resin systems than other high-boiling point cross-linking agents; in addition, the addition of film-forming agents and high-boiling point cross-linking agents will increase manufacturing costs, which is not economical

experiment example 1

[0035] The environment-friendly polyester molding composition includes 60 parts by weight of unsaturated polyester resin, 150 parts by weight of calcium carbonate as filler, 60 parts by weight of glass fiber, 0.5 to 10 parts by weight of initiator and 60 parts by weight of additive. In the experimental example, the high-temperature initiator is selected from tertiary butyl peroxybenzoate, and the medium-low temperature initiator is selected from 1,1-bis(tert-butyl peroxide)-3,3,5-trimethylcyclohexane, The mass ratio is 2:1; the molding temperature is 135°C to 145°C. According to the ASTM D5116 standard method, and detected by gas chromatography mass spectrometry, the dissipation rate of styrene is 1320 μg / m 2 ×hr, the estimated average daily absorbed dose (Lifetime Average Daily Dose, LADD) of styrene is 700-800 μg / day. The additives can be selected from at least one of polymerization inhibitors, low shrinkage agents, tackifiers, release agents and colorants.

experiment example 2

[0037] The ingredients and dosage ratio of the environment-friendly polyester molding composition are the same as in Experimental Example 1, the difference is that the high-temperature initiator is tertiary butyl peroxybenzoate, and the medium-low temperature initiator is 1,1-bis(tert-butyl peroxybenzoate). oxide)-3,3,5-trimethylcyclohexane, the mass ratio is 2.5:1; the molding temperature is 135°C to 145°C. According to the ASTM D5116 standard method, and detected by gas chromatography mass spectrometry, the dissipation rate of styrene is 228 μg / m 2 ×hr, the estimated LADD of styrene is 134.1 μg / day.

experiment example 3

[0039] The ingredients and dosage ratio of the environment-friendly polyester molding composition are the same as in Experimental Example 1, the difference is that the high-temperature initiator is tertiary butyl peroxybenzoate, and the medium-low temperature initiator is 1,1-bis(tert-butyl peroxybenzoate). oxide)-3,3,5-trimethylcyclohexane, the mass ratio is 1.6:1; the molding temperature is 137°C to 145°C. According to the ASTM D5116 standard method, and detected by gas chromatography mass spectrometry, the dissipation rate of styrene is 30 μg / m 2 ×hr, the estimated LADD of styrene is 15-25 μg / day.

Abstract

The invention discloses an eco-friendly polyester molding composition and a method for manufacturing a plastic board. The eco-friendly polyester molding composition includes 50 to 100 parts by weightof unsaturated polyester resin, 50 to 250 parts by weight of a filler, 50 to 200 parts by weight of glass fibers and 0.5 to 10 parts by weight of two initiators. The two initiators include a high temperature initiator and a low-to-medium temperature initiator which are mixed in a mass ratio of 0.5-4:1. A plastic board prepared from the eco-friendly polyester molding composition can effectively reduce the escape speed of volatile organic compounds.

Description

technical field [0001] The invention relates to a molding composition, in particular to an environment-friendly polyester molding composition and a method for making a plastic plate using the composition. Background technique [0002] Today, forest resources are depleting day by day, and many countries prohibit logging and exporting logs in order to protect the ecological environment, resulting in high prices of log products (log furniture). Wood-like plastic products have been widely used instead of wood in recent years because they are not easy to rot, have no disadvantages of odor caused by weathering and corrosion of traditional wood, and have no problem of moths. As the name suggests, wood-like plastic products refer to plastic products that are close to logs in texture, appearance and even mechanical properties. Common applications include building materials, decorative materials and furniture. [0003] In the prior art, there are wood-like plastic products made of sh...
